Heat a large skillet over medium heat. Toss the ramps or scallions with 1 tablespoon olive oil and season with kosher salt. Sauté until just wilted, about 1 minute. Transfer to a cutting board and cut into pieces.

Mix the ricotta, lemon zest, the remaining 1 tablespoon olive oil and some sea salt and pepper in a bowl. Brush Croccantini with extra virgin olive oil, then spread with the ricotta mixture and season with sea salt. Top with the ramps or scallions. Return to the oven until warmed through, about 2 minutes.
